Automated client-server data validation

ABSTRACT

The present invention provides a way to validate data entry at both the client and the server with minimal engineering effort. The system allows the specification of data validation rules for a form on a server. The system provides a version of the rules with the form to the client computer. The system also executes the rules on the server for further validation. The system may translate the rules into JavaScript data structures, passed as the version to the client for client-side validation. Because the rules for the form are specific only once, there is no possibility of the rules becoming out of sync betwen the form on the client and on the server.

TECHNICAL FIELD

[0001] This invention relates to checking the validity of data entry in web-based Systems.

BACKGROUND ART

[0002] In web-based systems involving data entry, there is a problem in checking the validity of the data. The prior art provides three choices, each having disadvantageous consequences:

[0003] 1. Check the data only at the client. This lets you be responsive to the user (you can display helpful messages in a timely way), but leaves your system open to bad data from entities that bypass your client and speak directly to your server.

[0004] 2. Check the data only at the server. This ensures that the server does not accept bad data, no matter what client is used to send it, but is harder to use because it may take a while to display messages to the user when data is incorrectly entered.

[0005] 3. Check the data at the client and at the server. This is responsive to the user and is safe from bad data, but requires a lot of engineering work because the data validation code has to be maintained on two platforms.

SUMMARY OF THE INVENTION

[0006] The present invention provides a way to validate data entry at both the client and the server with minimal engineering effort.

[0007] The system allows engineers to specify data validation rules for a form on a server. The system provides a version of the rules with the form to the client computer. The system also executes the rules on the server for further validation. The system may translate the rules into JavaScript data structures, passed as the version to the client for client-side validation. Because engineers only specify the rules for the form once, there is no possibility of the rules becoming out of sync between the form on the client and on the server.

[0008] A set of validation rules can be specified for each form (web page where data entry is allowed). Each rule is associated with a form element (e.g. the users email address or a phone number) and defines what is allowed and what is required for that form element.

[0009] Each rule can be created from a set of reusable, configurable constraints.

[0010] There is a set of pre-written constraints. New constraints can be added. Currently there are number constraints and string constraints.

[0011] Number constraints produce rules that force a field to be numeric and may also specify minimum and/or maximum values that the user must meet. String constraints produce rules that may have minimum or maximum lengths, may allow only certain characters, may require certain characters and may or may not allow white space (e.g. spaces, tabs).

[0012] Each supported constraint consists of server-side Java code and client-side JavaScript code.

[0013] When the server sends the form down to the browser it includes some JavaScript data structures, which are automatically generated from the set of rules that were defined for the form. When the user attempts to submit the form, some JavaScript code first iterates through each rule that was included in the automatically generated data structures. Each rule is checked against the appropriate entry field. If there is a violation of the rule, the JavaScript code immediately displays a message without involving the server. The generated data structure includes message text for each rule that can be displayed if the user violates a rule.

[0014] When the server receives a posted form, it iterates through each of the rules defined for that set. If there is a violation of the rule, the server responds to the client with an error message.

[0015] These and other advantages of the present invention will become apparent upon reading the following detailed descriptions and studying the various figures of the drawings.

[0077] Note that rule 16 is associated with form entry 12 and form entry 22. An example of a rule which is associated with more than one form entry would be a rule which validates that birth date and age must be close to each other. A birth date entry indicating an age of 16 and an age entry of 21 should fail such a validation rule.

[0104] Such operations may be performed as program steps residing in memory accessibly coupled to a development computer. The development computer may further be a server development computer or a client development computer. The server development computer may further belong to the server system containing the server computer.

[0109] Note that the associated validation rule set may be comprised of at least one associated validation rule.

[0110] Each of the associated validation rules may be associated with at least one form entry of the form collection.

[0111] Each rule may be created from a set of reusable, configurable constraints.

[0112] There may be a set of pre-written constraints. Currently there are number constraints and string constraints.

[0113] New constraints may be added.

[0114] Number constraints produce rules that force a field to be numeric and may also specify minimum and/or maximum values that the user must meet. String constraints produce rules that may have minimum or maximum lengths, may allow only certain characters, may require certain characters and may or may not allow white space (e.g. spaces, tabs).

[0115] Each supported constraint consists of server-side Java code and client-side JavaScript code.

[0116] The system may translate the rules of the form into JavaScript data structures, which are passed to the client for client-side validation of the form entries and the system also executes the rules on the server for further validation of the form entries. Because engineers only specify the rules once for the form, there is no possibility of the rules becoming out of sync between the form on the client and on the server.

Operation 496 terminates the operations of this flowchart.

[0122] The server may send the form to the client computer. The client computer may be operating a browser receiving the sent form as shown in FIG. 5. The form may include some JavaScript data structures. The JavaScript structures may be automatically generated from the set of rules defined for the form.

[0123] When the user attempts to submit the form, some JavaScript code may first iterate through each rule that was included in the automatically generated data structures.

[0124] Each rule is checked against the appropriate entry field. If there is a violation of the rule, the JavaScript code immediately displays a message without involving the server. The generated data structure includes message text for each rule that can be displayed if the user violates a rule.
